Here it is but you can't have it

Of late I hace come across this Windows shocker.

Open Windows Explorer and search for something. On average, if it's on your hdd, Windows will find it. However, I have had occasions when I have known something was there but I had to refine the search to get at it.

Sometimes,  twice yesterday, this happens ... enter your search term and wait. Windows shows you one or more files so you click one to open it and it says, I kid you not, Windows cannot find that file ... Explain that!

Another Windows Explorer niggle comes when I want to refine my search ab initio by, eg, saying, only find xlsx or pptx files ... usually such a choice is not available to me. Then sometimes it is ... not very often, though.
